Chromatography, including liquid and gas chromatography, is a staple tool in biological research. Preparative chromatography is used in the purification of proteins, antibodies, pharmaceuticals, bioactive compounds, and even cell populations. Meanwhile, analytical chromatography enables the measurement of target analytes and also the discovery of new compounds. Products in the scope of the chromatography application include packed (or empty) columns, chromatography media like resins or beads, filtration and concentration devices, kits, and accessories. The chromatography mode is the physical or chemical means of separation, such as via affinity binding, ionic interactions, hydrophobicity, or size exclusion.

Chromatography, the separation of mixtures by passing a mobile phase through a stationary phase, is a common technique used in most clinical and research laboratories. Media, the substance of the stationary phase, can be packed into an empty tube, also known as a column, by a laboratory technician. Empty columns are available for purchase which can then be used and discarded, or cleaned and used multiple times. The appropriate column will depend on the sample type, the purification method and the laboratory system. Mixtures can be separated by gravity, vacuum pressure or centrifugation. Small scale applications can be done with minimal sample volume; large production, or bioprocess, can be done on a manufacturing scale.
